Beasts of War has done a nice primer on the game itself ...
Our gaming group has been playing for six to eight weeks now and we've really enjoyed it. There are some bits here and there in the rules that have frustrated some of the players, the way small aircraft work, the seeming wide variation in terms of usefulness of units (bang for the buck/points as it were) ... but all in all there is near universal positive views on the game in our group. We haven't done the land portion of the game yet and by no stretch have we seen every unit in the game in action. Between a five regular player group (with three or four other occasional players in the mix) we have probably around forty or so games under our belt as a group and no one has quit yet :) Always a good sign. We've been talking garage league/campaign perhaps ... we'll see. I still don't know if the game will stick for sure or not to be honest as we have a group that is horribly afflicted by ADD and just kinda flaky at times. It has been a good way to get people doing some actual mini gaming though and for that reason alone I'm pleased and feeling like the money I've spent so far has been worth it.
Here is a rough shot of the gaming table that I built for it ... I'll get some more up as I've also been in a major game room move (moving out the the more spacious garage).
